This invention relates to linkhooks for use in connection withsmgledz-rees, draft-rlgglng, etc., of various kinds, and the main ob ectof the invention is to provide a hookfor engagement by a non-flexiblelink, ring'or eye for holding the latter in such a manner. that 1tcannot become accidentally disengaged therefrom.

A further obj ectof the invention is to provide a link-holding hook forgeneral purposes which requires the link to be applied to and 1 removedfrom the hook in a prescribed manner, and in which the hook is protectedagainst interference with or from other ob jects and from being cloggedby Inud or other obstructions.

The invention consists of the features of construction, comblnatlon andarrangement of parts, hereinafter fully described and claimed, referencebeing had to the accompanying drawing, in which Figure 1 is a top planView of the device as employed as a single-tree hook, a portion of-asingle-tree being shown.

Figure 2 is an end elevation thereof.

Figure 3 is a horizontal section on line 3-3 of Figure 2.

Figure 4 is a vertical transverse sectionon A line 1 1 of Figure 3.

V in applying and removing it and its operative Figure 5 1s a viewlooking toward the mouth of the guard, showing in broken and full lines,respectively, a position of the link position when applied. 7 v

The device shown in the present instance, as designed for use upon asingle-trecor other draft bar, beam or element A, is U- shaped toreceive and en'ibracethe endo-f the element A and comprises side cllpsland 2 bearing against opposite sides of the element A and an endclip13fjoiningsaid side clips and engaging the extremity of the elementA,

the device being secured in position by one or more bolts or otherfastenings 4 passing through the clips 1 and 2. 7

The side clip 2 and adjacent side of clip 3 form a support for a hook 5and a guard 6, which hook is adapted to be engaged by a rigid link 7attached to a trace or other draft element '(not shown), a link ofoblong form casting, if desired.

of the hook and guard are obtained. A clearance open1ng'1 5 1s provldedattheinner end being shownzin the present'instance. The

parts 1, 2, 3,5 and .6.

may be formed as a single As shown, the shank 8 of the hoe-k5projects'outwardly from and at right angles to' a cross -piece8vformingthe outer end of clip 1 J 2 and a side of c1 P While the binlorlpoint of the hook projects toward the clip 2 and forms .an opening10 in the clip 2 inwardly beyond theinner edge of the cross-piece 8, between which portionsjofthe clip. 2 and hook '5athroat or passage 111 isformed for-the passage of the link?- into and out of engagement with theopening of the hook. I

of the hookifor the passage of mud or debris, such opening preventingclogging of the hood and rendering-it self-cleaning when theparts in'useare dragged'through mud or other obstructions. w l Thedistance betweenthe plates 12,as well asthedistance between thehook and portion of theguard overhanging the same, is'l'ess than the width of the link 7, andhence the link can only beengaged withior disengaged "from the hook by aprescribed movement. To'engage thelink with the'hook the link is turnedto aposition substantially parallel with thefplane of the hook and-in'sert'ed through o'neor the other of the passages 14 until'itsinnerend entersthe passage 15,

whereupomby turning the link at adiagonal angle to the plane of thehook, as shown in broken lines in Fig; 5, the link may be movedthroughthe passage 15 and throat 11 F P Ar EfN'Ti Jerice: 1;,

The guard 67 comprises a pair of sideplates 5 into the opening of thehook and then disposed in its normal working position shown in fulllines in Fig. lVhen thus engaged it is practically impossible for thelink to be come accidentally disengaged and the link can only bedisengaged by reversing its applying movement above described; While,therefore, it is easy to manually engagethe link-With or release itfromthe hook, accidental disengagementof the link, cannot occurnotwithstanding any slackness which may be present between the link andthe hook. i

By the construction described the device may not only be fa'stenedfirmly'to'a si'rig'gle tree or other: draftelement, but, as the bill 7ofthe hook is Wholly enclosed-by the guard,

theirouter edges beveled to gradually increase their: depth between thebase of hook and the hood.

\ In testimony whereof I aflix my signature I osoAR A. sToRAAsLL thehookis protected against- Weeds or trash I 7 being caught and choking theguard and interii'ering jvith the free relative movements of theconnected parts, the connection is made safer, clogging by mud or otherforeign.sub.

' stances is prevented, 'andease andconven-ience of operation isensured. While the.device is described in connection with a Whifiletree,

it may, of course,'be used in logging, mining,

r Jandin various kinds oflrigging inshippin-g, v hauling andconstruction Work, and for many 7 7 other purposes.
